Abstract
Goggles include a pair of eyepieces, an elongate nosepiece connecting the pair of eyepieces to form an assembly, and a fastener securing the assembly on a wearer's head. The nosepiece has a flexible bridgepiece adapted to pass over the bridge of the wearer's nose and, at each end of the bridgepiece, an end ring defining an aperture. Each of the eyepieces is rigid and defines a lug extending inwardly towards the bridgepiece and a pin disposed rearwardly of the lug and extending inwardly. The lug defines a passageway therethrough for a respective one of the end rings, and the pin is configured and dimensioned to enter and engage the aperture of the respective one end ring. The pin and lug cooperatively preclude accidental disengagement of the end ring aperture and pin, whereby the nosepiece and eyepieces are releasably locked together to form the assembly.
